Optical Candidates for A0353-40 and A0535+26

D. R. Soderblom, Lick Observatory, reports that coude spectrograms (range 5800-6800 A, dispersion 34 A/mm) obtained with the 305-cm reflector show that star 1 in NGC 5367 (Van Till et al. 1975, Astrophys. J. 198, 235), the diffuse reflection nebula close to the error box for the x-ray source A0353-40 (Cooke 1976, Nature 261, 564), exhibits strong H-alpha emission peaks at ~ -160 and ~ +70 km/s and a pronounced central absorption at ~ -60 km/s No other stellar or interstellar lines are apparent, and there are no peculiar features in the spectrum of NGC 5367 star 2. Similar observations of the Be star DD +26 883 = HDE 245770, the suggested optical counterpart of A0535+26 (IAUC 2780, 2784), show very strong H-alpha emission (FWHM ~ 300 km/s) centered at ~ -32 km/s, a slight reversal at ~ +42 km/s and no stellar absorption lines. The B-V color (IAUC 2790), together with the reddening value derived from the diffuse interstellar features at 5780 and 5797 A, confirm that the star is of spectral type O or early B. Both BD +26 883 and NGC 5367 star 1 would bear close spectral examination at shorter wavelengths.
